Board dilemma...

After some more advice...
Off to the coast tomorrow forecast is 3-4 ft (chest high) at my level of ability and confidence this is my limit for my 'improving but poor' paddle fitness / skills to get out
Last time I went in these conditions I was knackered after getting out once and cut session short which was a little frustrating.
I have two boards (pics below) 7'2' x 221/4 x 3 and 6'6 x 22 x 2 13/16 get on well with both and paddle fine to catch waves with both (I'm 63kg 5'4) Use the 7'2 for smaller days and if I haven't been in for a while. Whilst the 7'2 is easier to paddle I find it tough getting out through the impact zone the 6'6 is harder to paddle but more manageable getting through waves.
I know that ultimately I need to continue improving paddle conditioning which I'm doing following the advice from good folks on here, but that's not going to change before my session tomorrow and I really want to nail a longer session, so which board do you think I'll have more success with?
Thanks in advance
